How do I go from a range to a list of values:

range := /[30..35]/ // Does not amount to /[30,31,32,33,34,35]/

Also, what's the reason the following mapping can not be chained to a filter:

fahrenheitTemps := /[30,31,32,33,34,35/] celciusTemps := fahrenheitTemps.map(Int[,]) |Int v->Int| { return (5/9)*(v-32) } frozen := celciusTemps.findAll( |Int v->Bool| { return v < 32 } )

Invalid args findAll(|sys::V,sys::Int->sys::Bool|), not (|sys::Int->sys::Bool|) ERROR: cannot compile script

Thanks in advance, Casper

Casper,

There isn't a convenience method on Range to go to a List, although I'll add a Range.toList method for next build. Until then you need to do something like:

list := Int[,]
(30..35).each |Int i| { list.add(i) }

Regarding the map issue - it is because without any other explicit type declaration, the result of map will be Obj[], not Int[]. You can fix with this code:

fahrenheitTemps := [30,31,32,33,34,35] 
Int[] celciusTemps := fahrenheitTemps.map(Int[,]) |Int v->Int| { return ((5f/9f)*(v.toFloat-32f)).toInt } 
frozen := celciusTemps.findAll |Int v->Bool| { return v < 32 }
echo(frozen)

However findAll should work against Obj[] just fine according to newly defined rules. That is something I still need to fix. See previous discussion.

Thank you very much Brian. Continue the great work! :)
